The subsequent Artemis 1 launch try would possibly happen as quickly as subsequent week, seeing as NASA has met all of the aims it got down to do to think about its rocket’s gas take a look at successful. NASA needed to take a look at including super-cooled gas to the Area Launch System’s tanks to substantiate the repairs it made after it scrubbed the mission’s second launch try in late August. The bottom crew at Kennedy Area Middle noticed a persistent hydrogen leak affecting one of many gas traces on the SLS on the time and tried to repair it the day of thrice. Ultimately, the crew was unsuccessful and determined to postpone the mission.
The crew decided a couple of days later that the leak was triggered when the SLS rocket’s core booster tank went via a quick overpressurization. To forestall the identical incident from taking place, the crew adjusted procedures for filling the rocket’s tank with propellants, and it entails transitioning temperatures and pressures extra slowly to stop speedy adjustments that would trigger leakage. The crew’s engineers additionally changed the rocket’s liquid hydrogen seals after discovering a small indentation in one in every of them that will have contributed to the leak.
Whereas the engineers encountered one other hydrogen leak throughout the gas take a look at, their troubleshooting efforts labored this time round and acquired the leak to “inside allowable charges.” That allowed them to conduct the pre-pressurization take a look at, which introduced up the liquid hydrogen tank’s strain degree to match what it will expertise simply earlier than an precise launch.
Artemis 1 launch director Charlie Blackwell-Thompson stated the take a look at went “very well” and that the crew was capable of accomplish all of the aims it got down to do. NASA will now consider knowledge from the take a look at earlier than deciding if it may possibly schedule one other launch for the mission on its goal date of September twenty seventh.
